Abstract: A platform (1) allows end users to engage in a session with servers such as content providers, corporate systems, commercial services or ASPs. A session object is associated with each session, attributes of which include the channel—thereby allowing changing of a channel during a session. Request/event objects are associated with the session object as requests/notifications arise, and these objects are shared with other modules. Hosted services may be physically resident on the platform or may be accessed transparently via interfaces. A device/channel neutral mark-up language extended from a presentation mark-up language is used as a single common form from which the delivered content is derived. The content from a service is generated by an executable process, normally (but not exclusively) in the extended mark-up language. The derivation of deliverable content is performed via a dynamic and configurable sequence of providers that manipulate the original content in stages.

Abstract: A document transformation system (1) comprises a layout server (2) which dynamically generates output documents for delivery to a user device. The layout server (2) selects a layout template (5) according to user device and delivery channel characteristics and fragments from source documents (6) are inserted into the layout templates (5). Information to assist with selection of a template (5) is retrieved from a user device information repository (3).

Abstract: In a server a source document is represented as a source document object model (13). For delivery of the source document to a user device such as a mobile phone the server dynamically selects transformation maps (10) and merges them to provide a compound map (12). The maps (10) are selected according to characteristics of the delivery channel and of the user device. The source DOM (13) is then transformed into a target DOM (14) in a single pass. Each node of the source DOM (13) self-transforms using the map rules. At the node level the transformation may change node attributes and/or node-to-node relationships.
